We've got a birthday party coming up here next week and we spent a couple of hours in our local big box craft store. We didn't know what we were looking for, exactly, but were confident that we'd find something fun for a small gaggle of kindergarteners to make that didn't involve glue or paint and would be sure to be successful, So, fabric markers on canvas drawstring bags! I must have picked up puffy, or sparkly fabric paint bottles a dozen times. I ought to be congratulated for not ambushing an elegantly simple craft with wet gooey stuff that didn't have time to dry before parental pick-up time. Really. Congratulations to me!
So, I had to try them out...
